no diagnostics for german

[arantxax]

Describe the bug
I just downloaded ltex+ as ltex-ls to use as command-line/offline/stand-alone grammar checker. The first run should take long enough, but it seems that the server initialization is taking too long or has too many threads working on. For english text works fine.

Steps to reproduce

1. Download ZIP file: ltex-ls-plus-18.2.0-windows-x64
2. Extract it in your desktop.
3. Create a "test" directory in your desktop.
4. Create a simple test.tex file in the "test" directory.
5. Copy the folder "ltex+" in the as subfolder in "test".
6. Go to "test\ltex+\ltex-ls-plus-18.2.0\bin"
7. Right click on the directory and select "open in Terminal"
8. ./ltex-cli-plus.bat ../../../test.tex --client-configuration=".lsp-cli.json" --verbose

Expected behavior

I want the server to be initialized and correct the grammatical errors in the tex document.

**Sample document**
This is the specific document in LaTeX:

\documentclass{article}
\usepackage[ngerman]{babel}
\begin{document}

\selectlanguage{ngerman}  % Explicitly set language to German
%Three banana.
Ein Satz auf Deutsch Sprache.

\end{document}

LTeX configuration
Configuration settings from .lsp-cli.json:

{
  "programName": "ltex-cli-plus",
  "helpMessage": {
    "description": "LTeX CLI - Command-line interface for LTeX LS",
    "visibleArguments": [
      "--client-configuration",
      "--verbose"
    ]
  },
  "defaultValues": {
    "--hide-commands": true,
    "--server-command-line": "ltex-ls-plus.bat"
  }
}

Additional context/information

UPDATE:
By writing "Ein Satz auf Deutsch Spraches." with an extra S in the end, the diagnostic is released and, therefore, I am able to correct the grammar error. I'm not really satisfied, because the previous test "Ein Satz auf Deutsch Sprache." was wrong too. It should have corrected for: "Ein Satz auf deutsche Sprache."
I know that the grammar rules are outside of this fork's scope, so I'll close the issue and work on a bigger test.

I can confirm that LTeX+ CLI is running endlessly if there is no spelling mistake. I will try to find a solution.
Regarding the sentence "Ein Satz auf Deutsch Sprache.": The correct repo to address this issue is https://github.com/languagetool-org/languagetool
